Hi,
I just thought I would arrogantly post something you guys may or may not
be aware of:
As was mentioned in another thread,
The Kernel Developers have removed /devfs from the linux-2.6.13.x series
kernels, so I would expect it to be gone from any future kernel starting
with the 2.6.13 series.
What this means is:
1) You will need to install udev (or something like it) for the device
filesystem. If you merely compile the 2.6.13.x kernel, and try to boot
with it without having udev installed, you will probably find that in
99% of the cases, you will not boot up at all.
2) Doing some research on udev (without going into configuring udev's
rules), I find that udev makes device links only for the devices that it
detects on boot. Most of the X windows startup failures I have heard
about are due to the /dev/mouse or /dev/psaux links no longer being made
by udev, and X suddently cannot find your pointer device. The solution
that I know most people have done, including me, is to change the
/dev/mouse device in the xorg.conf, or XFConfig-4 files to
/dev/input/mice (mice seems to be preferred as that actually seems to
change to always point to the active mouse in your system, rather than
using /dev/input/mouse). Now, I know a you can make a link to the real
device yourself in the directory, but you run the chance that udev may
not make that link at any given bootup, especially if udev doesn't
detect the device.
Hope you find this helpful.
